Inequalities of Dirichlet eigenvalues for degenerate elliptic partial differential operators

Na Huang, Jingjing Xue

Let $X_{j}, Y_{j} (j = 1, \cdot \cdot \cdot, n)$ be vector fields satisfying Hörmander's condition and $Δ_{L} = j = 1 \sum n (X_{j}^{2} + Y_{j}^{2})$ . In this paper, we establish s…
